There are tons of markets that don't exist because people just don't want to allow a market – for whatever reason, people feel icky about putting a price on something. For example: Surrogacy is a legal industry in parts of the United States, but not in much of the rest of the world. Assisted end-of-life is a legal medical transaction in some states, but is illegal in others.When we have those knee-jerk reactions and our gut repels us from considering something apparently icky, economics asks us to look a little more closely. Today on the show, we have three recommendations of things that may feel kinda wrong but economics suggests may actually be the better way. First: Could the matching process of organ donation be more efficient if people could buy and sell organs? Then: Should women seek revenge more often in the workplace? And finally, what if insider trading is actually useful? *This episode was hosted by Mary Childs and Greg Rosalsky. It was produced by Willa Rubin and edited by Jess Jiang.
